Even if you disregard the lowest tier of Windows Vista — the totally lame “Starter” version that only runs three apps at a time — the next highest tier sucks too. This isn’t good for Windows users, and it isn’t good for PC makers, either. Microsoft must think it’s good for themselves, but I seriously doubt that — they might make money from people upgrading from the crummy lower tiers, but at the expense of the company’s brand.
